Ventricular tachycardia mapping and ablation in arrhythmogenic right ventricular cardiomyopathy/dysplasia: Lessons Learned

Figure 7 Epicardial right ventricle free wall activation maps illustrating propagation wavefront of epicardial isolated potentials in a patient with arrhythmogenic right ventricular cardiomyopathy/dysplasia. A: Right ventricle (RV) free wall activation via a broad wavefront progressing toward the inferior RV; B: A diverging pattern of activation, initially broad, but subsequently branching as it progresses through the scar; C: Reverse centripetal pattern with outside activation progressing inward with wavefront collision in the center of the scar.
